,Applicationfiled -April 24, 1919. Serial No. 292,398.

To all whom it mag "camera r Be it known that I, WILLIAM MACK, a citizen of the United States, a'rid'a resident of the city of New York, borough of .Manhattan, in tliexcounty and State of New York, have invented a new andfImprov'ed Aquarh um, of which the following is a full, clear, and exact description. l

The'object of the invention is to provide a" new and: improved aquarium which is simple and durable in constructionand not'lia'ble to get out of-order easily, "-Another object is to render the aquarium wa tertight;

- 711311 these and other objects in .view, the

invention consists of certain novel features of Construction as hereinafter shown and described and then specifically pointed out in the claims. l

A practical embodiment of the invention is represented in the accompanying drawings forming .a part of thisspecification, in which bottom 15 andthe sides 16 being preferably similar characters of reference indicate cor-' respondingp'arts-in all theviews.

Figure-1 is a' perspective view of the aqua- Figi2 is an enlarged sectional perspective view of-a portion-of the aquariu m;-

Fig. 3 isa sectional plan view of the .corner fastening for fasteningthe ends of adjacent sides together; j 1 The one-piece supporting frame 10 of the aquarium is preferably of metal, rectangular in shape, and the. frame s provided at its outer margin With a depending annular flange 11, from which extends outwardly an annular ledge 12 provided at the corners with depending legs 13 for supporting the aquarium-on a stand, table'or other suitable support. On the frame 10 rests abottom 15 and on the ledge 12 rest the sides 16, thesaid made. in the form of. glass plates. The ends -of adj acentsides abut one against the other,

' and the lower portions of the sidesab-ut with their inner' faces against the annular flange -11 and against the edges of the bottom15. {In order to'fastenthe' lower portions of the sides 16 .to the frame flange 11 use is made of angle or cornerclips 20, one for each .50.

corner,and fittingexteriorly on the'end p0"- tionsof adjacent sides 16 and the flange 11 t-o'fasten the said parts together, as will b.e readily understood by reference to Fig: 2. "Similar angle or corner clips 25 fit exteriwithout the aid of highly skilled labor.

' In-order to render the various joints watertight land to allow expansion and contraction of the parts Without openingthe .j oint's', use is made of waterproof cement interposedbetween the bottom edges of the sides 16 and the ledge 12, betweenithe inner faces of the sides 16, the flange 11 and the edges. of the bottom 15, between the bottom 15 and the frame 10, between the abutting ends of adjacent sides, and between the clips 20 and"; 25 and the outer faces of the sides 16.

The bolt holes inthe sides 16 and flange 11 are filled with a cementitious substance to prevent direct contact of the metal parts V with the glassparts and thus compensate forthe unequal expansion and cohtraction of the metal and gla'ssparts.

Having thus described my invention, 1 claim as new and desire to secure by Let ters Patent 1.v An aquarium, comprising a metal base frame having a depending annular flange terminating in an outwardly extending annular ledge and supporting legs depending from said annular ledge, a bottom resting on the said base frame, glass sides'seated on the :said ledge and fitting against the. frame a flange and the edges of thesaid bottom, cor-e ner clips fitting exteriorly onto adjacent ends 790 of the said. sides opposite the said frame flange, and bolts passing through the said corner clips, the sides and the frame flange v to fasten the parts together. i

2. An aquarium,-"'comprising a metal base 9 frame having a depending annular flange terminating in anoutwardly extending an said ledge and fitting against the frame fitting exteriorly on the vadjacent ends of the flange and the edges of the said bottom, corsaid sides near the upper ends thereof, aiid' ner clips fitting exteriorly onto adjacentends bolts passing through the upper corner clips 10 of the said sides opposite the said frame and the said sides to fasten the latter'to- 5 flange, bolts passing through the said corner gether.

clips, the sides and-the frame flange to fasten the said, parts together, upper corner clips WILLIAM MACK.
